Abstract: 1,001,793. Seaming non-metallic sheet material. COMMUNICATIONS PATENTS Ltd. May 24, 1962 [June 2, 1961], No. 19927/61. Heading B5K. A device for welding thermoplastic sheets 1, 2 comprises a central shoe-like live electrode 6, a pair of shoe-like earthed electrodes 7, 8 arranged one on each side of the electrode 6, all mounted for alignment of the soles thereof on one side of a planar surface of the sheets 1, 2 and co-operating with a metal surface 5 on the opposite side of the sheets 1, 2. The sheets 1, 2, e.g. of polyvinyl chloride, having respectively undercut and bevelled edges are placed on a table 3 with these edges abutting to overly an aluminium foil strip 5. The electrode 6 is positioned over the join 4 and the electrodes 7, 8 lie above the strip 5 near the edges thereof. The field passes from the electrode 6 through the sheets 1, 2 in the region of the join to the strip 5 and returns through the sheets near the edges of the strip to the electrodes 7, 8. The underneath surface area of electrodes 7, 8 is at least twice that of the electrode 6 which is radiused at 6<SP>1</SP>. In one embodiment, Fig. 3, the electrode 6 slides along the join 4 and comprises a copper shoe having a spigot 17 engaging in a block 18 with springs 19 bearing on the upper face of the shoe. A polytetrafluoroethylene band 10 passes around rollers 11, 12 mounted on a carriage 15 to prevent adhesion of the thermoplastic material to the electrode 6. A double hookshaped tension spring 16 urges a shaft 13 carrying the roller 11 forwardly to tension the band 10. In a modification, Fig. 4, the electrode 6 is provided with polytetrafluoroethylene side cheeks and the band 10 of fibreglass impregnated with polytetrafluoroethylene is tensioned by a jockey pulley (not shown) bearing thereagainst.

N-Carbobenzyloxy- S-benzyl-L-cysteinyl-O-alkyl-L-tyrosyl-L -phenylalanine azide is prepared by reacting N-carbobenzyloxy-S-benzyl-L-cysteinyl-O-alkyl-tyrosine with L-phenylalanine methyl ester hydrochloride to form the tripeptide methyl ester, reacting this with hydrazine to give the hydrazide and this with nitrous acid.

Abstract: 1530053 Data transmission PHILIPS GLOEILAMPENFABRIEKEN NV 13 May 1977 [18 May 1976] 20195/77 Heading H4P A receiver 1 for data signals transmitted by the double sideband quadrature modulation of a carrier wave is provided with a detection circuit 4 which, starting from a first value, assumes a second value on the receipt of synchronizing signals and reverts to the first value after a "training" period which follows the synchronizing period. The transition from the first value to the second value is used to synchronize the receiver with the incoming signals, whilst the transition from the second value to the first value is used to effect a correct preadjustment of an adaptive equalizer 3 associated with the receiver. As shown, the detection circuit 4 comprises a bandpass filter 7, a zero crossing detector 8, a pulse-interval measuring circuit 9 for producing the required first and second values on outputs 10 and 11, and a pulse analyser 12 which provides the control signal for equalizer 3. The Specification explains with reference to Figs. 2 to 7. (not shown) how this arrangement enables the transition from the synchronizing period to the "training" period to be accurately detected whereby the adaptive equalizer is brought into correct operation with the minimum of delay.
